1851 Address Unknown, Lexington, Missouri.
1852 Rooms over Mr. Miller’s Boot and Shoe Shop, Glasgow, Missouri.
1853 Address Unknown, Independence, Missouri.
W. B. Howell was recorded in one announcement and one advertisement. The announcement appeared on October 14, 1852 in the Glasgow Weekly Times (Glasgow, Missouri). All persons wanting an exact likeness of themselves, should call on Mr. W. B. Howell, over Mr. Miller’s boot and shoe store shop, where he is prepared to take Miniatures in all the late improvements in the art. He invites the ladies and gentlemen of the city to examine his specimens whether wanting likenesses or not.
The Advertisement appeared on December 10, 1853 in the Occidental Messenger (Independence, Missouri). Look Now For Fine Daguerreotypes!! Mr. Howell would respectfully call the attention of the ladies and gentlemen of Independence and vicinity, to the fact that he has just fitted up his room in good style, so that he is able to furnish those wishing it, A Splendid Likeness. As he is going away for a few weeks, he will leave Mr. J. H. Twyman in charge of his rooms, to operate during his absence. Mr. Twyman is a splendid operator—in fact to do him justice he is surpassed by none in the Art. I therefore do not at all hesitate in recommending him to the people as an Artist. As he has been with J. H. Fitzgibbon of St. Louis, he has all the new styles of operating, and all the late improvements that are now known in the business.
I will also say to the people, that there are at my room a splendid assortment of cases, which he will [sell] on moderate terms. Oct 29th, 1853. W. B. Howell.
W. B. Howell is recorded in Craig’s Daguerreian Registry and Pioneer Photographers from the Mississippi to the Continental Divide A Biographical Dictionary, 1839-1865 as being active in 1851 in Lexington, Missouri.
